ROBERT MCKAY, OF DETROIT, MICHIGAN, ASSIGNOR TO THE MCIIAY NEVERSLIPSOLE COMPANY, OF SAME PLACE.

CUSHIONED HEEL-PLATE FOR BOOTS OR'SHOES.

SPECIFICATION forming part of Letters Patent N o. 598,714, datedFebruary 8, 1898. Application filed J'nly 21, 1897. Serial No. 645,316.(No model.)

To all whom, it may cortccrn:

Be it known that I, ROBERT MGKAY, a citi- Zen of the UnitedStates,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Cushioned Heel-Platesfor Boots or Shoes, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention consists in the combination of rubber with a non-elasticlight body or core of peculiar shape and embedded in the rubber in suchmanner that that portion of the heel-plate which receives the directimpact in Walking is of solid rubber and thereby forms an eectivecushion, While the remaining portion is combined with the non-elasticbody in such manner as to form a better and surer footing than anall-rubber plate would do, all as more fully hereinafter set forth andshown in the drawings, in Which i Figure l is a vertical centralsection-thro ugh a shoe-heel provided with my improved cushionedheel-plate. Fig. 2 is a horizontal section on line @c 0c in Fig. I. Fig.3 is a detached perspective view of the versed.` f

A is the leather heel of a shoe to which my heel-plate is applied andwhich leather forms a complementary portion of the heel and is composedof the rubber portion B and of the non-elastic body or core C, embeddedin it. The non-elastic body C is truncated in such manner that it onlyforms a core in the for` ward portion of the heel-plate, with the rub-4ber forming an even covering or skin around it, While the rear portionis constituted of solid rubber, substantially in the form of a segmentor crescent.

The non-elastic body is preferably a blockm of Well-seasoned `WOQQMQ.@-lghthandm .tough charact'e'r for the purpose of making the plate lightand u nitingitwith the rubber by the usual proiess of vulcanizing it ina mold. Other materials which are the equivalents of wood, however, maybe used in lieu thereof.

The heel-plate is to be secured to the heel f heel-plate rein the aboverespects by means of nails driven through the wooden core, and in orderto properly mark the place at which they should be driven I mold acountersink a for each nail through the outer covering of rubber, sothat the nail-heads may be sunk and concealed and will take a firm holdof the Wood. I also form afeW countersinks b in the solid-rubber portionof the heelplate. These` extend about half-Way into the rubber, and thenails which are driven into these countersinks may be provided withlarge heads or washers but preferably washers c are for this purposeembedded permanently in the rubber, as shown in Fig. 2. To make the heelantislipping, I also form it with a few marginal rows of protuberances dor with a roughened border.

My improved heel-plate is light, durable, and noiseless. It forms aneective cushion just where it is needed-that is, at the rear portion,where,the impact is produced when the heel touches the ground first inwalkinganda limited cushion at the remaining portion, where ar greatercushion would produce an insecure footing and tire the ankle in Walking.My construction is thus a decided improvement over such heel-'plates inwhich a non-elastic body extends over the rounded portion of the heeland wherein it receives almost the full impact and is subjected to sucha heavy strain that metal has to be used unless the entire heel is madewith a core.

What I claim as my invention is- In a cushion-heel for boots or shoes,the combination of a heel-plate of rubber conformable to the heel andadapted to form a complementary part thereof and a truncated heel-plateof non-elastic material embedded therein and forming a core for theforward portions of the rubber plate, the segmental rear portion beingof solid rubber. i

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT MCKAY.
